best way to sign leases online?

Hi all! I currently have 2 single family homes that I rent out to stable, long-term tenants. So far, it's been easy to meet up with them in person to sign leases every year. There are so many page on the lease due to my state being complex that it's nice to read through it in person, etc.

However, I will be expanding and will have 4-5 doors in the next year. The new ones will be right by my house. I would like to consider switching to an online method. I collect rent with Zillow, and it has worked just fine. I use lease forms specific to my city/state that i have access to through my state real estate investor's association. So, I want to use my own forms and have different forms for different cities. Is DocuSign a good app? Google workplace? Any other suggestions? Should I use a platform other than Zillow that will do it all?
